switchdev: convert parent_id_get to switchdev attr get
Switch ID is just a gettable port attribute. Convert switchdev op switchdev_parent_id_get to a switchdev attr. Note: for sysfs and netlink interfaces, SWITCHDEV_ATTR_PORT_PARENT_ID is called with SWITCHDEV_F_NO_RECUSE to limit switch ID user-visiblity to only port netdevs. So when a port is stacked under bond/bridge, the user can only query switch id via the switch ports, but not via the upper devices Signed-off-by: Scott Feldman <sfeldma@gmail.com> Acked-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S.
